The traditional unit of measurement for radiation exposure is known as?

• A. Gray
• B. Roentgen
• C. Curie
• D. Rad

Answer: (B)

The traditional unit of measurement for radiation exposure is known as the Roentgen. This unit specifically measures the amount of ionization produced in air by X-rays or gamma radiation. The Roentgen is defined in terms of the ionization produced in a specific volume of air at standard conditions, which makes it particularly useful for assessing radiation levels in various environments, including dental and medical settings. The significance of the Roentgen lies in its historical use, as it was one of the first units established to quantify the immediate biological effects of radiation. This helps professionals gauge how much radiation patients or staff might be exposed to during diagnostic procedures. Other units, although related to radiation measurement, serve different purposes. The Gray is a unit that measures absorbed dose, while the Curie is a unit of radioactivity that indicates the rate of decay of radioactive materials. The Rad, similar to the Gray, is another measure of absorbed dose but is considered less relevant today due to its older definition. Thus, the Roentgen remains the traditional and established unit for evaluating radiation exposure directly.
